1,078,97 Y. Staines To dummer my email@- Be itkno'w' that"` I, ,En citizen of theUnited States', `e

State-of Missouri, have invented ya ,new and`- useful Steam-Trap; and I do Lherebvjweclare the following to be a full, clear, and exact description of the invention, s uch as will enable others skilled in the art to which it appertainfs to make and use the same, 4

This invention relates to afnew and useful steam trap.

As one of the objects of th-e invention it ,is the aim to provide a trap of this nature, .adapted for use in connection with low pressure apparatus, it being' the design of the invention to discharge the water from the trap without the loss of more than an ounce of steam. 4

Particularly the trap is adapted for luse in connection with heating coils, vats or tanks, where low pressure steam is used, and through experience it has been found that it handles condensation of steam as fast as it is supplied, thereby keeping` full pressure on the heating coils or'tanks. l There are disclosed in the drawings cer'- tain features of construction, but in practiscal ields, these features may necessitate alterations, to which the patentee is entitled, provided the alterations fall within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :-Figure 1 is la vertical sectional view through the improved'trap. Fig. 2 is a cross sectional view.

Referring more particularly to the drawings 1 designates-a cylinder, which may be of any suitable dimension or proportion. Fastened to the upper end of the cylinder by means of bolts 2 is a cap plate or head 3, there being suitable packingl 4, in order to insure the steam tight connection..` A nipple tube 5 is `threadedl or otherwise secured .in the cap plate or'head,`as shown at 6. The

-nipple tube is supplied with an air cock or valve 7 for allowing the escape of air. An inlet pipe 8 connects to the cylinder 1, for feeding steam tothe same. The lower end ofthe cylinder 1 terminatesy in an annular iiange 9, which is arranged adjacent, another ange 10, there being bolts 11 for securing ther cylinder and the attendant' parts siin-gtsu f Joseph, in the -c'ou'ntyvof 'Buchanagwand comme f ,y @any formY of heating cdils, vats'or 'tanks' to the 4stern 15 of'which an arm 16 is secured. vSliela'ble upon the arm 16 is a'collar 17, held i`n adjusted positions upon the arm 16 by the set screw 17 a. 'To this collar the flexible end 18 of the rod 19 is pivotally connected. The upper portion or extremity of the rod 19 is guidedn the nipple tube as it moves vertically. Slidable loosely upon the rod 19 is any suitable construction of iioat 20. On the rod 19 immediately labove its flexible end portion 18, and fixed below the float 20 by means of tlieset screw 20 isa collar 20h, which supports the float 20, above the iiexible end 18. Arrangedv upon the rod 19, the same being held in adjusted positions by a set screw 21 is a collar 22. This collar may be set at any llocation upon the rod 19, according to when it is desired .that the valve 14 should open to allowthe water in the cylinder 1 to escape;l The steam enters the cylinder 1 by way of the pipe 8, and as the steam condenses, the water settles inthe botmtom of the cylinder, and if the collar 22 is set at a on the'rod 19 and the water reaches a level as indicated at a1, the float 20 will contact withl said collar 22 and raise the rod Vvertically, which in turn will open the valve 14 and permit the water to escape through the pipe 12. However, the collar 22 may be set at b on the rod 19, and when the water rises to a level-as indicated at b1, theiioat 20 will contact with the collar 22, in order to raise the rod, which' in turn will actuate the valve14,"to allow the outiiow of the water.

*Ani outltfpipe12"extends-lfro1i1thein. `terior' ofthe"cyliider"1,and Yterminatesat `any suitable'locatinupon `the exterior 'of the-j f 1- cylinder#Thispipe1'12'isprovided with valve easing "13 having the-usual vvalve-14,-

The object in adjustably connecting the lower flexible end 18 of the rod.: 19 to the rod 16, is to increase or decreasethe throw of thevvalve 14, in opening and closing. T he object for allowing the valve to open at different levels of the water in the cylmder 1, is to allow an attendant cfa low pressure plant to adjust the trap, according to the nature and the operation of such a plant.l

It is tobe ascertained from the foregoing that there has been devised a simple and e cient steam trap and onpwhich has' been found more particularly? adapted for use m commotion y upon low pressure apparatus, owing to the practicability of the construct`on. i y The inventig'm having been set forth, what ,fis claimed as new and useful isz-4.

In a steam trap, a cylinder having a steam inlet and provided with an outlet pipe hav` ing a valve, said valve hajving an arm movable therewith, av nipple tubeA including an air cock connected to the cylinder, a rod movable in said cylinder with its upper portion slidable in the nipple tube and having a lower flexible end, a collar 'mounted on said larm towhichthe lower extremity of said flexible end is pivotally connected, said collar adapted to be adjusted in diii'erent posiin a device for holding the same adjusted; a oat slidable on said rod, a collar on said rod above its flexible end and fixed ybelow the iioat, a second collar arranged adjusttions to vary the" throw of the valve includ
